Dot-Tune: Autofocus Fine Tuning in under 5 minutes
Got to agree with NCAndy. I was thrilled to find the Dot Tune method. Told all of my friends, etc. After the MA, everything seemed good, then I'd go out shooting and yuk - soft. After trying multiple times over months, I gave up. I had FoCal which was buggy. So, I pretty much just "eyeballed" it. Then version 2 of FoCal came out and Perfect!!!!
If you use Dot Tune and get reliable results - good for you. I won't argue with you. I would get different results with Dot Tune EVERY time I tried it. Usually small differences but enough to not get the razor sharpness that I expected. As of now, my friends have stopped using it as well. Just get too much variability with Dot Tune. I wish the Dot Tune method worked for me - it's cheap and easy.
